在JQueryEasyUI中为DataGrid自定义了一个ComboGrid编辑器。具体方法：

自己写一个扩展

$.extend($.fn.datagrid.defaults.editors, {

    combogrid: {

        init: function (container, options) {

            var input = $('<input type="text" class="datagrid-editable-input">').appendTo(container);

            input.combogrid(options);

            return input;

        },

        destroy: function (target) {

            $(target).combogrid('destroy');

        },

        getValue: function (target) {

            return $(target).combogrid('getValue');

        },

        setValue: function (target, value) {

            $(target).combogrid('setValue', value);

        },

        resize: function (target, width) {

            $(target).combogrid('resize', width);

        }

    }

});

定义DataGrid

<table id="tt1" class="easyui-datagrid" singleselect="true" idfield="MaterialReceivedEntryID"

    fit="true" striped="true" rownumbers="true" fitcolumns="true" showfooter="true">

    <thead>

        <tr>

            <th field="ItemID" width="80"

                formatter = "itemFormatter"

                editor="{

                type: 'combogrid', options: {

                    required: true, panelWidth:260, fitColumns:true,

                    idField:'ItemID', textField:'Code',

                    url:'<%= Html.AttributeEncode(Url.Action("GetRMItems", "Item")) %>',

                    columns:[[

                        { field: 'Code', title: '物料代码', width: 80 },

                        { field: 'Material', title: '材质', width: 80, align: 'center'},

                        { field: 'Diameter', title: '直径', width: 60, align: 'center' }

                    ]],

                    onSelect:function(rowIndex, rowData) {

                        $('#tt1').datagrid('updateRow', {

                            index: _lastIndex, row: {

                            Material: rowData.Material,

                            Diameter: rowData.Diameter } })

                    }

                }

            }">

                原材料代码

            </th>

            <th field="Material" width="80" align="center">

                材质

            </th>

            <th field="Diameter" width="60" align="center">

                直径(mm)

            </th>

            <th field="Long" width="60" align="center" editor="{ type: 'numberbox', options: { required: true}}">

                长度(mm)

            </th>

            <th field="ReceivedQty" width="60" align="center" editor="{ type: 'numberbox', options: { required: true}}">

                根数(PCS)

            </th>

            <th field="Weight" width="60" align="center" editor="{ type: 'numberbox', options: { required: true, precision: 3}}">

                重量(T)

            </th>

            <th field="HeatNumber" width="100" align="center" editor="{ type: 'validatebox', options: { required: true}}">

                炉号

            </th>

            <th field="Remark" width="80" align="center" editor="text">

                备注

            </th>

        </tr>

    </thead>

</table>

最后别忘了那个Formatter

function itemFormatter(value, row) {

    ... ...

}
